It's a board-to-cable/wire interconnect — a through-hole vertical header that mates with the matching Micro-Fit 3.0 receptacle housing and crimp terminals. The 3.00 mm pitch and 8 A per circuit rating put it in the moderate-power class: it handles DC rails and moderate loads, not just signal lines. Gold on the mating interface (30.0 µinch) and tin on the solder post (100.0 µinch) — the gold gives you repeated mating cycles without corrosion, the tin is for a reliable solder joint. The -40°C to 105°C operating range and UL94 V-0 housing back that up — it's at home in an engine bay, an industrial cabinet, or a medical device enclosure. The locking ramp and board lock mean it stays put under vibration, which is why you see Micro-Fit 3.0 in harness assemblies for power distribution and control systems. The 8 A per circuit at 600 V is the headline — at 3.00 mm pitch, that's enough creepage for the voltage without forcing an oversized board footprint. This header mates with the Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) using the matching crimp terminals (43030 or 45750 series for 20-24 AWG). The through-hole termination is straightforward: kinked solder pins insert into a 3.00 mm pitch PCB layout, and the board lock holds it during soldering. No press-fit tooling needed.","metaTitle":"Molex 430452426 Micro-Fit 3.0 Header, 24 Pos, 3mm, 8A","metaDescription":"Molex 430452426 Micro-Fit 3.0 24-position dual-row header, 3.00mm pitch, through-hole, gold mating contacts, 8A per circuit, 600V, UL94 V-0, ROHS3.","metaKeywords":null},"attributes":{"series":"Micro-Fit 3.0 43045","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":[],"specifications":{"Style":"Board to Cable/Wire","title":"430452426","Series":"Micro-Fit 3.0 43045","Package":"Tray","Features":"Board Guide, Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Kinked Pin, Solder","description":"CONN HEADER VERT 24POS 3MM","Applications":"Automotive, General Purpose, Industrial, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.118\\\" (3.00mm)","Voltage Rating":"600V","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.390\\\" (9.91mm)","Base Product Number":"043045","Insulation Material":"Liquid Crystal Polymer (LCP), Glass Filled","Number of Positions":"24","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.125\\\" (3.18mm)","Current Rating (Amps)":"8A","Operating Temperature":"-40°C ~ 105°C","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.47","priceTiers":[{"qty":1,"price":"$8.47000","currency":"USD"},{"qty":10,"price":"$7.36300","currency":"USD"},{"qty":80,"price":"$6.07475","currency":"USD"},{"qty":1152,"price":"$5.04386","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2cd00626506f7b62e7853978b7a4cb8e.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/430452426/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch of Molex 430452426?","answer":"The pitch is 0.118\" (3.00 mm) on both the mating interface and the row spacing — a standard Micro-Fit 3.0 footprint."},{"question":"Is 430452426 RoHS compliant?","answer":"Yes, it is ROHS3 compliant per the lifecycle record."},{"question":"What is the current rating of 430452426?","answer":"Rated 8 A per circuit at 600 V — the 8 A figure is per-contact, so a 24-position header can carry up to 192 A total across all circuits, derated per the temperature rise curve."},{"question":"What is the mating receptacle for 430452426?","answer":"It mates with the Micro-Fit 3.0 receptacle housing (43025 series) using the matching crimp terminals (43030 or 45750 series for 20-24 AWG wire)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/430452426","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/molex/430452426 when reusing this data.
